Question

I have the following HTML code

<li><div><..><input type="submit" ...></div></li>

i added a click event to the button to remove the Whole <li>. the process takes a while 1/2 second sometime. I wanted to include a message with a wait icon while processing removing I code the following code:

   var $li = $(btnRemove).closest( li ).empty();

    // Add Please wait
    var $logo = $( <img> ).attr( src ,  logo.gif );
    var $tblWait = $( <table /> ).append(
            $( <tr /> ).stop()
            .append($( <td/> ).append($logo))
            .append($( <td/> ).html(  Pleasee wait while removing table ))
            );
    $li.append($( <div/> ).append($tblWait));

..... Process and do other tack and finally
$li.remove();

如果一把小点一带,我就会看到标识和标识;如果电文没有破碎,则在1/2秒之后,电离层就会被拆除,但电 log不会打上。我试图将图像上装在页面准备活动上,但标识实际上很小,没有时间装上。任何帮助都将受到高度赞赏。

这是因为贾瓦伦古文的性质,而多瑙河则有着同样的线索。一旦你们对人力部做出任何改变,能源部将不再停下来。这一过程可能会看上去:

(idle) -> Event fires -> JavaScript code executes -> Repaint GUI -> (idle)

为了显示这一信息,你需要利用时间来拖延漫长的过程:

$li.append($( <div/> ).append($tblWait));

window.setTimeout(function () { 
    //... Process and do other tack and finally
    $li.remove();
}, 0);
